GAS JOINT OR SEAL FOR CLOSET-BOWLS.

Specification of Letters Patent.

Patented Augb *7, 191W.

Application filed August 21, 1916. Serial No. 115,990.

To all whom t may concern:

Be it known that I, JOHN R. WILLIAMS, a citizen of the Dominion ofCanada, and a resident of the city of New York, borough of Manhattan, inthe county and State of New York, have invented a new and Improved GasJoint or Seal for Closet-Bowls, of which the following is a full, clear,and exact description.

This invention relates to seals or joints for closet bowls and has foran object the provision of an improved construction which will preventleakage of sewer gas and which is automatically maintained in a properoperating or workable condition.

Another object in view is to provide a seal at the bottom of the bowlarranged as a trap and acting in connection with a specially constructedbowl for supplying the trap with fluid.

A still further object in view is the production of an improved bowlhaving a vent or passageway and projections coacting with a pocket orcup structure of the waste pipe whereby a gas trap or seal is producedwhich is automatically supplied with water each time the bowl isflushed.

In the accompanying drawing:

The figure is a side view partly in section of a bowl and trapdisclosing an embodiment of the invention.

Referring to the accompanying drawings by numerals, l indicates the bodyof the bowl which may be of any usual or preferred structure, which isprovided with a passageway 2 leading to the waste pipe 3. In forming thebody 1 a passageway 16 is provided which follows the outline of theouter face of the bowl, preferably, and eX- tends from slightly belowthe overflow or dam 18. Passageway 16 discharges into the pocket 7inside of the flange 9 and allows for a free circulation of air throughthe passageway from either end so that the same will not become airbound and prevent the free flow of water to the sealed pocket.

By this construction and arrangement, whenever the closet is flushedsome of the water will pass through the passageway 16 and into thepocket 7. The pocket 7 is formed by an annular cup 8 which is bolted orotherwise secured to the bowl l and a1'- ranged to have the annulardepending flange 9 project therein, said flange being formed integrallywith the bowl l as well as the guiding flange l0. The cup 8 may be madeseparate or independent of the waste pipe 3 and then soldered thereto,but usually and preferably the waste pipe 3 is made integral with thecup 8, as shown in the drawing.

IVhat I claim is:

l. A water closet bowl comprising a bowl body having the usual trap, apassageway leading therefrom, means defining a second passageway leadingfrom the top of the trap to the bottom of the bowl, and a seal or traparranged at the bottom of said bowl for receiving water from said secondpassageway.

2. A bowl of the character described, comprising a body having a wastepassage, a liquid gas seal surrounding the outlet of said passage, andmeans defining a passageway from the upper edge of the water seal of thebowl to said seal around said outlet whereby each time the bowl isflushed water may pass to said seal.

8. A water closet bowl comprising a body having a waste passage formedwith a trap and a pair of spaced annular depending flanges surroundingthe outlet of said waste passage, a liquid gas seal surrounding saidoutlet, said seal having a pair of upstanding walls telescoping overpart of the outer of said flanges, and means defining a passageway fromthe upper edge of said trap to the interior of said outer fiange wherebywater will be supplied to said gas seal each time the bowl is iiushed.

4L. A closet bowl of the character described, comprising a body having awaste passage and a depending annular flange surrounding the wastepassage but spaced therefrom, a liquid gas seal telescoping over saidflange, the outer wall of the seal eX- tending to nearer the base of theflange than the inner wall, and means defining a water passagewayextending from the water line of the trap in the first mentionedpassageway to a point immediately within said flange whereby wheneversaid trap is flushed water will pass through said last mentionedpassageway into the trap for maintaining the trap filled, said innerwall permitting an overflow from the trap.
